allow more overrides of template code

NOTE: I don't think this commit directly affects network, since
network doesn't use any of these - this PR is more for parity
with template and other repos.

Centralize the setting of `ME` and `TOPDIR` in utils.sh

Add support for `RUN_FLAKE8_EXTRA_ARGS` and `RUN_BLACK_EXTRA_ARGS`
